摘 要

隨著電力電源的快速發(fā)展，功能要求越來越高，電源監(jiān)控系統(tǒng)的智能性也在不斷的更新提高。基于此，本文設(shè)計(jì)了智能電源監(jiān)控系統(tǒng)。
系統(tǒng)采用STC12C5A60S2系列單片機(jī)作為微控制器，系統(tǒng)由主監(jiān)控人機(jī)接口與顯示、電流信號(hào)的采集、電壓信號(hào)的采集、報(bào)警電路、繼電器觸點(diǎn)保護(hù)電路以及下行通信等模塊組成。電路流檢測模塊實(shí)現(xiàn)對(duì)交流電壓和電流的不間斷實(shí)時(shí)檢測，并對(duì)電源系統(tǒng)進(jìn)行實(shí)時(shí)監(jiān)測。當(dāng)發(fā)生故障時(shí)，進(jìn)行報(bào)警提示，并通過通信總線傳輸?shù)街鞅O(jiān)控單元，從而實(shí)現(xiàn)智能監(jiān)控。
此模塊能夠很好的完成檢測功能，并且具有良好的經(jīng)濟(jì)性。
本文通過對(duì)交流檢測模塊的軟硬件進(jìn)行了相應(yīng)的設(shè)計(jì)和調(diào)試，完成了畢業(yè)設(shè)計(jì)所要求的任務(wù)。

ABSTRACT

With the rapid development of electric power, the function demand is higher and higher, power monitoring system of intelligent is also in constant updates improve. Based on this, the paper designed a intelligent power monitoring system.
System uses STC12C5A60S2 series microcontroller as micro controller, system by the main monitoring man-machine interface and display, pay current signal collection, voltage signal collection, alarm circuit, relay contacts protection circuit and downlink communication module. Circuit flow of inspection module realize the ac voltage and current detection in real time, uninterrupted power supply system of real-time monitoring. When malfunction happened, alarm prompt, and through communications bus transfers to the main monitoring unit, so as to realize intelligent monitoring.
This module can be good finish detection function, and has good economy.
This article through to exchange detection module the hardware and software of the corresponding design and commissioning, completed the graduation design requirements of the task.
Keywords：Intelligent power monitoring; STC12C5A60S2 microcontroller; Exchange detection and control.
